Table 4 Computational balance for the three categories of HT

From: Line and circle detection using dense one-to-one Hough transforms on greyscale images

 
  1. Row 1: one-to-many HT computed on a contour image and used with a fine grained quantised parameter space. Row 2: many-to-one HT computed on a contour image and used with a coarse grained quantised parameter space. Row 3: one-to-one DHT computed on the greyscale and used with a coarse grained quantised parameter space
